I have a 1994 90 hp evinrude model # E90TLERC.<br />While going to the NGK sight for plugs they have two versions of the 90 hp, L4 & C4. Can you tell me which one I have and maybe the plugs I should use.

Use Champion spark plugs # QL77JC4 or QL82C The 82 is hotter and if you are fouling plugs at low speed, goes with that one. Stay away from NGK, as they do not perform well in OMC units. Gap at .030 unless you troll alot. If so, set them to .040 gap. Start off with the QL77JC4's first and see how it does..
